I've had a couple of the electrodynamics a123 cells go bad when I did not understand how to correctly use the batteries , it was my fault for leaving them plugged into the plane for a month . I've tried to cycle A123 but found once they are gone they are really gone. The one thing that will kill a a123 for sure is letting the battery get too low or dead . once in this state they never seem to come back . Another thing you need to be aware of is they need to be balance charged every time , and like mentioned above you need to be on the correct setting . Too high a charge from being on the wrong setting will also destroy them .I'm not saying you cant destroy them but but with a simple understanding of the way the batteries work they will last for years . Nathan you need to understand what you've done to the battery to cause it to fail .

This is what I do and never have problems anymore .

Never deep cycle A123 , Many chargers will discharge the battery too far and destroy the battery before you even use it ..

Never fast charge A123 . max 500mah on the 1100 and 1a on the 2300 cells

Always balance charge a123 ..

NEVER let them go dead or overcharge or they will fail..

Re: Bad Receiver Batteries

I just scrapped a receiver pack last night while checking my planes over for the season. It was a 4.8 2600mah pack that is at least 15 years old. It showed 4.34 volts after sitting in my basement for the winter. When I tried to charge it the volts went up quickly and the charger kicked out. I dropped the charge rate to 100mah with the same result, voltage on the pack went to high to charge. Its not worth playing around with as I always have new packs to use. Cheers Floyd
